I dont have much experience in 3v3 but Ill try to do my best. Ganking would be really hard imo, even without wards. Also most melee heroes are out, with no one to lane them. I would probably go something like potm/wr long lane, cm solo mid and furion short lane. Get a couple of ganks off with furion, cm nova spam mid. Anyway. As I said not a lot of experience.

1 . pick one hero from each Agi , Str , and Int , pick the agi carries ..
and the str must be a war initiator and a tanker ( ex : levi , centa , tiny , magnus , etc .. well , i recommend levi because it can be a good tanker and his ulti is a widest AoE spell in dota ), the Int must be a support nuker , ( ex : zeus , lich , akasha , etc , i recommend lich because the cf is really good for semi-war initiator )

2 . pick based on hero roles , note that a support wont always be int , an str/agi can be a support too
- carry , semi-carry ( well , it must be a ganker , ex : viper , venom ) , support ( i use this a lot when i dont have enough player to play 5v5 )
- carry , carry , support ( this is a risky play , but if u are good enough , u can pawned ur enemies in late game )
- and there is still so many of them

3 . pick on combo , always remember to balance the team , dont pick all str just because it has a good combo . ex : nevermore , magnus , darkseer .

hope this helped u , i'm still a newbie on this game, but i will do my best ^_^

Some hints about 3v3 :
-disables are great. By disabling one ennemy, you disable 1/3 of its team instead of 1/5. Therefore Bane is often adviced.
-Strong solos are recquired, no matter what strat you want. The game will most likely be decided by who powns who in lane (not necessarily kills, but oufarming and outlveling).
-Push can be easier, as they have to totally give up a lane or 2 if they want to help def. Therefore, Lycan and Brood, who are also strong solos, can be nice.
-Having some mobility can help, but it's not compulsory. Like a good Furion who can often gank with tp, but beware of not letting your opponent too much freefarm in lane.
-You shouldn't suffer a gank, if your allies warn you when one ennemy is missing, cuz it's immediately seen.

Void kunkka lich ultcombo is pretty funnnnnnnn
Kunkka can be replaced with tiny if you insist on stuns, but any of them will do.
Ints can also be replaced by other who have more disables, but CF+wellplaced chrono is epic plus he haz armor.

lol ta for the replies but you guys are thinking too advanced. this is like a casual tourney at my college and most ppl there are noobs and the prize is only like R100 (or about $15 in american terms). so theres no real strats here im just trying to think of nice combos. previously we used like panda sven bara etc

Meepo for epic 6(7) vs 3,beware of lich/shaker and creepskip axe.
A mid bat or appa ganking nonstop.
Fill the last spot with anything.Aoe stunner for more control,luna or venge for effingmeeposdeimjover9000andshit,NA or TA for OMGICANTEVENFARMNEUTRALS or a hard carry to ensure lategame victory.
Edit:Special mention Dazzle.Heal + meepos=dead.Cold feet+poison touch=dead.Shallow grave+ally=not dead.

Teh Furion is extremely stronk in 3v3 matches. In this little match I had, their Furion player managed to outpush us (and I was playing Lycan no less) and despite he being meat for wolves in the end we lost all our raxes to endless waves of treants before I ever destroyed his. I call that unfair

Weaver would probably be a top pick in 3v3. He owns a 1v1 lane and he owns late game hard. Also he's a lot harder to kill with only 3 players.

I'm not very sure about the rest. There are so many good choices that come in mind after a bit of thinking: Omniknight, Shadow Demon, Doom, Furion, Windrunner, Broodmother, Shadow Fiend, Balanar. Then there are the heroes usually not seen in serious games that get stronger the fewer players there are in the game: Slark, Slardar, Bane, Barathrum, Meepo, Bristleback, Huskar, etc.

I guess there's no use theorycrafting it, you are just going to have to play 3v3 and find out the best strategies yourself. I can only give you a list of suggestions.

Furion is self explained, everyone knows he's ganking ability.
Bane is mid for reasons of tower and creep dps with Sleep + Ult combo.
(Sleep enemy while u clear enemy creeps, Ult him when your creeps move to attack him).
Razor/Slark long because they can kill any hero solo in long lane.

Furion is already pushing power...no need for any other push hero because his TP ability out's them all.

Bane is great solo, and best in 3v3 fights. Sleep one, ult the other, leave the last guy to die. Also, if Razor is in team, you can Link the sleeping Hero to drain his DPS while you DPS the awaken Hero. (Great combo).

Razor/Slark's job is to only delevel the other Hero allowing Furion to TP and kill so he can PUSH, PUSH!, *POP*, IT'S A BOY!!!. Essence shift out's any enemy 1v1. Same with Static Link. Because they are going to be underleveled, Furion can just TP in to kill.

Weaver fighting against Razor or Slark is bad. Though he can go invis, Razor and Slark can out dps Weaver. With lack of HP, Slarks Essence shift ability (The fact that it LOWERS max hp by stealing STR) will kill Weaver faster than Weaver's dps. Razor just needs to dps and Link after he invis's. With mana cost very low for Link, Razor can keep harassing causing Weaver will not get exp.

After him there are a lot of good heroes, such as Weaver, Clock (who shreds most 3v3 picks), Tinker, Bara (who isn't that bad at soloing). 3v3 is all about global presence, laning and momentum, get heroes which provide that. Disablers suck dick in 3v3, generally.
